2021 RST Crew Cab Wind Noise at Door Seals

I know that I can't be the only one that has a leaking door seal allowing wind noise in my 2021 Silverado RST 3.0 Duramax Crew Cab 4WD. I tried searching this forum but didn't find anything. I searched the internet and don't see my issue either.

 

I have had both front door gaskets replaced twice and it still hasn't fixed the wind noise in the cab. I know they're leaking because I have driven down a dusty road and you can see where the dust entered between the seals.

 

I have had two different dealers change out the seals. I know that I'm not the only one because my dealer told me that they have worked on others and some are fixed afterward and some are worse. I just had them changed today for the second time and it's as bad as it was or worse. It's hard to tell because it's very windy outside today. The rear doors don't seem to leak.

 

When the wind is calm outside, I can't hear it leaking but if I drive in a crosswind then it really leaks bad.

 

I don't know what to do from here but I'm still not satisfied. I hate it too because this little pickup is everything I want; great ride, looks good, all the comfort that I want, fantastic fuel mileage, and shifts great with the 10 speed.

 

Makes me want to pull a Thelma and Louise at the closest cliff.

I have this issue on my 17. The problem with mine is the frame of the door around the window is inset of the front pillar. I believe there was a tsb... In this tsb, the fix was to put something between the door and the cab (window rolled down) and flex it to the appropriate shape 😬 At the time I decided I didn't trust anyone enough to do this, and now I can't hear it over the exhaust so it doesn't matter. 

 

Anyways, I'd recommend checking out the alignment. Seals wont matter if the door isn't where its supposed to be.

I have the same issue with my truck and I'm extremely mad about this. Sounds like a train whistle right beside my ear.

      Blend door actuator

      By Charly · Posted

      Trying to replace the temperature control, blend door actuator in my 2005 GMC SIERRA 1500, but can NOT get to it by just removing the under panel on passengers side. It seems like I will need to remove the side panel of the center console, or the entire center console just to get to it- can anyone offer instructions, pictures, videos… step by step so I can get this done!??!! It’s TOO HOT to be without AC!

      I will be one of those "blinded". One, I like new shiny things. Two, I've never kept any of them beyond the 3/36. Three, I don't finance anything. Four, yep, it's a waste of money....so,what? I'm doing my part of keeping automotive industry going and keeping my neighbors, most of whom are in it, employed. 😉      By the way this is the "signature... ¬

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By marpel · Posted

      Although there is a "recommended" weight by those who sell trailers, my experience has been that they are way too aggressive in their information, for me at least. My '22 with 6.6 Gas, has a payload of about 3400 lbs and depending on your specs (I don't have 4WD so it has a bit higher Payload than others) yours will likely be different. Payload is one of the most important numbers for towing. Although you "could" tow the max trailer weight for your truck, I, personally, would not go close to that number. Having said that, a lot depends on how/where you will be towing. I live in the LMD of BC and often tow to Denver, Co, along interstates (flat and mountains) and I find I need to keep it in 5th (6spd) for the trip and travel at around 65mph. This is for a trailer dry weight of just under 3500lbs. If you are only doing local, short trips, it would not be that big an issue if you had a heavier unit. You will be surprised how much stuff you load the trailer with, so I would only recognize the trailers "full" GVWR weight rating, then decide on the appropriate trailer from that number. If you are worrying about how much stuff you should be putting in a trailer, you might have too large a rig from the get-go. Once again, depending on what terrain/distance in which you will be pulling. Marv

      Disconnecting Battery

      By marpel · Posted

      davester, Thanks for the response, how ever, I think I am now a bit more confused than I was before I posted - - After I posted, I actually found a YT video of a guy who replaced his Module (above tire) and he only disconnected the ground cable of the battery, but you describe rubbing the two cables together after disconnecting. I presume that is to do as you describe and eliminate any residual energy? - When I picked up the Module (between my posting and reading your response) from the dealer, I specifically asked about any re-programming and he stated it was not necessary as it was simply plug and play. Don't know how knowledgeable he is, though. - The video I watched also showed the Module plug to be difficult to "unlock" and remove, but there was no mention of silicone, although the video did show a bunch of dust/dirt in and around the plug (old truck) during removal. Are you talking about silicone that was applied by the factory, or silicone that you applied prior to plugging in? Thanks again, Marv
